Prediction of the formation and variation of oceanic fronts

发展了一种预报大洋锋面形成和变化的新方法。对于锋面密度和其他量的间断，采用了一种带梯度限制器的非振荡数值格式，充分地表示为不可压缩的N-S方程的有限体积解。验证了该方法的有效性，并与实验结果进行了比较，从而准确地预测了三维密度界面上的海洋锋面行为，从而对海洋环境进行了调查。

A new method is developed for the prediction of the formation and variation of oceanic fronts. The non-oscillating numerical scheme with a kind of the gradient limiters is implemented for the discontinuity of density and other quantities at the front represented adequately as the finite volume solution of the incompressible Navier-Stokes equation. The validation of the present method is made for the comparison of the experimental results to predict the behavior of the oceanic front for the three-dimensional density interface in such an accurate way to investigate the marine environment.
